Figure 5.6. Percentage time at sea spent in different FAO Statistical Areas while breeding for 11 species of albatross. Only those species for
which a large proportion (over 70%) of the global population is represented by satellite tracking data are shown.
Table 5.1. Percentage time at sea spent in selected FAO Statistical Areas while breeding for 16 species of albatross, two species of giant-petrel
and one petrel species for which satellite tracking data were submitted to the workshop.

2 The percentage of the global population tracked was calculated by summing the proportion of the global annual number of breeding pairs at each site for which tracking data was contributed.
3 Indicates whether tracking data was submitted for all sites containing over 1% or 5% of the global annual number of breeding pairs.
